A way to reuse an installed module or patch the one to be installed?

[x-yuri]

I'm trying to make use of PerlIO::eol under Alpine Linux (docker), but the way it is now, it doesn't work. However, there's a workaround: build it with OPTIMIZE => '-O0'. So I have two ideas in mind:

• Install PerlIO::eol before installing the rest of the packages (e.g. Video::Subtitle::SRT which depends on PerlIO::eol) with carton. And make carton not install its own copy of PerlIO::eol, which otherwise overrides the installed package.
• Make carton build PerlIO::eol with OPTIMIZE => '-O0'.

Is any of this possible? Any other ideas?
